Alfalfa (Medicago sativa) has often been referred to as the “Queen of Forages” because it is an excellent source of protein and digestible fiber, and because of its wide adaptation. Alfalfa has a high mineral content and contains at least 10 different vitamins and is an important source of vitamin A. Alfalfa improves soil tilth, and, in symbiosis with nitrogen fixing bacteria, is highly effective in converting atmospheric nitrogen to biological nitrogen. Thus, alfalfa is an ideal crop for use in crop rotation to improve soil tilth and replenish nutrients depleted from the soil by other crops such as corn.

The environment in which plants are grown for agricultural production continuously offers new obstacles to agricultural production, including, for example, changes in weather conditions, pests, and disease. Plant science agriculture involves manipulation of available plant resources to meet the needs of the growing human and animal populations. Each new cultivar or variety released to agricultural production is selected for the purpose of increasing yield resulting from increased disease resistance to prevalent diseases, or from direct or indirect improvement in yield potential or efficiency of production. Development of stable, high yielding cultivars with superior characteristics is an ongoing goal of alfalfa breeders.

Thus, there is a need in the art for a novel alfalfa cultivars and alfalfa seed.

In one aspect, the present invention provides a Medicago sativa seed or cultivated alfalfa seed designated Magnum VI and deposited under the terms of the Budapest Treaty and in accordance with 37 C.F.R. §§ 1.801-1.809 on Apr. 10, 2007 with the American Type Culture Collection (ATCC), Manassas, VA, under Accession Number PTA-8324.

In another aspect, the present invention includes a Medicago sativa alfalfa plant or cultivated alfalfa plant derived from the seed designated Magnum VI and deposited under Accession Number PTA-8324. The plant may be grown directly from the seed deposited under Accession Number PTA-8324, or may be obtained indirectly from a plant grown directly from the seed by any suitable methods. For example, the plant may be generated from seed produced by a plant grown directly from the seed, from a cutting taken from a plant grown directly from the seed, or from tissue culture or callous derived from cells from a plant grown directly from the seed. The invention includes succeeding generations of plants derived from plants grown from the seed of Accession Number PTA-8324.

In another aspect, the present invention provides tissue culture of regenerable cells from a plant, or parts thereof, produced by growing seed deposited under Accession Number PTA-8324 and designated Magnum VI and alfalfa plants regenerated from the tissue culture

In other aspects, the present invention includes the pollen and ovule of a plant derived from the seed deposited under Accession Number PTA-8324.

The present invention also provides a method for developing an alfalfa plant in an alfalfa breeding program using plant breeding techniques, comprising using an alfalfa plant, or part thereof, produced by growing seed designated Magnum VI as a source of breeding material.

Other features and advantages of the invention will be apparent upon review of the specification.

Not applicable.

Terms used in the descriptions and tables that follow are defined as follows:

Flower color: Modern alfalfas are characterized by flower colors: purple, variegated, white, yellow and cream. Some cultivars are heterogeneous for flower color whereby some are predominately purple and variegated.

Forage yield is measured by harvesting herbage for part of or the entire life of the stand.

Fall dormancy: Alfalfa is classified into fall dormancy classes numbered 1 through 10, where dormancy group 1 is very dormant suited for cold climates and dormancy group 10 is very non-dormant and suited for very hot climates in which the plant would grow through out the winter months.

Winter survival: This evaluation is a prediction of the ability of the plant to persist over time.

Persistence: The ability of the cultivar to last over a minimum of two years. This measurement is documented in the visual percent stand remaining at the time of observation.

Anthracnose: Anthracnose is a serious stem and crown rot disease of alfalfa which can kill individual plants and cause rapid stand decline. Anthracnose is caused by Colletotrichum trifolii, a fungus which produces masses of tiny spores on infected stems and crowns. During periods of hot, rainy weather, spores are splashed from infected to healthy plants. Lesions develop on stems, causing stems to wilt and eventually die. The pathogen grows from stem tissue into the plant crown, and causes a crown rot which ultimately kills the plant.

Aphanomyces Root Rot: Aphanomyces root rot is caused by the fungal-like pathogen Aphanomyces euteiches causes death and poor growth of seedling alfalfa in slowly drained fields. It also can be a chronic disease of established plants that may result in significant yield reduction. Aphanomyces root rot is similar to and may occur in a complex with Phytophthora root rot and Pythium damping off, diseases which also occur in wet or slowly drained soils. Plants infected with Aphanomyces usually are stunted and chlorotic before they wilt and die, whereas Phytophthora and Pythium tend to kill seedlings quickly before plants become severely chlorotic.

Bacterial Wilt: The disease is caused by Clavibacter michiganense subsp. insidiosum (McCulloch) Davis et. al.=Corynebacterium insidiosum (McCulloch) Jensen. The bacterium survives in plant material in the soil, hay and seed for several years. It can be spread plant to plant via surface water (rain) irrigation and contaminated implement. Bacterial wilt is most common on plants growing in low, poorly drained areas of the field. It is also more common in wet years. Primary infection occurs when bacteria enter roots via wounds. Wounding can be caused by insect or nematode feeding, winter injury of mechanical injury. Once the bacterium enters the plant, symptoms are slow to develop, usually visible in the second or third crop year.

Fusarium Wilt: This disease is caused by Fusarium oxysporum f. sp. Medicagines. Wilting shoots are the first evidence of the disease. In early stages, the leaves may wilt during the day and regain turgidity at night. Bleaching of the leaves and stems follows, and a reddish tinge often develops in the leaves. Only one side of a plant may be affected at first, and after several months, the entire plant dies. Dark or reddish brown streaks occur in the roots appearing in cross section as small partial or complete rings.

Phytophthora Root Rot: Phytophthora root rot is caused by a soil-borne fungus, Phytophthora medicaginis, which is present in most alfalfa field soils. This fungus survives in organic debris and becomes active in wet soil. Water-saturated soils allow production of zoospores which have the capability to “swim” to roots and begin the infection process. Infection usually occurs on small lateral roots. From these initial infection points, the fungus gradually grows into the taproot. A yellow, red, or purple discoloration of leaves is the most characteristic above-ground symptom of Phytophthora root rot. Damage is most evident in low or poorly-drained areas of a field.

Verticillium Wilt: Verticillium wilt is caused by a fungus, Verticillium albo-atrum, which enters the water-conducting cells of the alfalfa plant and restricts the upward movement of water and nutrients. The fungus produces spores within the plant, or on cut stem surfaces following harvesting operations. Spores germinate on the cut surfaces and produce filaments (hyphae) that grow into stems and ultimately into roots. Verticillium wilt symptoms usually do not become conspicuous until the third production year. A yellow, V-shaped discoloration at the tip of a leaflet is an early indication of Verticillium infection. Eventually, leaflets wilt, turn yellow or pink, and often curl or twist. These abnormally small, twisted leaflets occurring near the top of the stem are the most characteristic symptoms of the disease. Stems are stunted, but frequently remain green and erect (in contrast to the drooping stems caused by anthracnose). Taproots appear healthy and sound, but have a dark ring (the water-conducting tissues) which is evident when the taproot is cut in cross section.

Pea Aphid: The long-legged pea aphid Acyrthosiphon pisum (Harris) adult is light to deep green with reddish eyes. It has a body length of 2.0 to 4.0 mm and most adults are wingless. The cornicles (a pair of tailpipe-like structures projecting from the abdomen) of this aphid are characteristically long and slender. The egg is approximately 0.85 mm long; the light green egg turns a shiny black before hatching. The nymph, the immature aphid is smaller than, but similar to, the larger wingless adult. It requires four molts to reach the adult stage. Pea aphids extract sap from the terminal leaves and stem of the host plant. Their feeding can result in deformation, wilting, or death of the host depending upon the infestation level. Plants that survive heavy infestations are short and bunchy with more lightly colored tops than those of healthy plants. Wilted plants appear as brownish spots in the field. Moreover, plants are often coated with shiny honeydew secreted by the aphids, and cast skins may give the leaves and ground a whitish appearance.

In one aspect, the present invention includes the seed of alfalfa cultivar Magnum VI deposited under the Budapest Treaty and in accordance with 37 C.F.R. §§ 1.801-1.809 on Apr. 2, 2007 with the American Type Culture Collection in Manassas, VA as Accession Number PTA-8324, and plants or plant parts derived from the seed deposited as Accession Number PTA-8324.

By “a plant derived from the seed deposited as Accession Number PTA-8324”, it is meant a plant that is grown directly from the seed deposited as Accession Number PTA-8324, or a plant that is obtained indirectly from a plant grown from the seed deposited as Accession Number PTA-8324. Plants obtained indirectly from a plant grown from the seed deposited as Accession Number PTA-8324 may be grown from a vegetative cutting, seed, callus or tissue culture obtained from a plant or plant part grown from the seed deposited as Accession Number PTA-8324 or a clonal plant thereof.

Magnum VI has superior characteristics and is a 121 clone synthetic. Parent clones were selected out of forage yield plots and/or disease nurseries. The parent plants were progeny tested for one or more of the following traits: forage yield, stand persistence, forage quality, resistance of bacterial wilt, Fusarium wilt, Phytophthora root rot, anthracnose (Race 1), Verticillium wilt and Aphanomyces root rot (Race 1). All of the parent plants trace back to Dairyland experimental plants. Parent plants were planted in field isolation and inter-pollinated by honey (Apis mellifera), leaf cutting (Megachili rotundata) and bumble bees (Bombus impatiens) near Sloughhouse, Calif. in 2001 to produce Syn. 1 as Breeder seed. Seed from parent plants were equally bulked each year to produce Breeder seed.

Breeder seed (Syn. 1) was produced by bulking seed of parent plants which were grown in field isolation near Sloughhouse, Calif. in 2001. Seed from parental clones were equally bulked. Foundation seed (Syn. 2) was produced from Breeder seed and Certified seed (Syn. 2 or 3) from either Breeder or Foundation seed. One generation each of Breeder, Foundation and two generations of Certified seed classes are recognized. A maximum of three harvest years each is permitted on stands producing Breeder and Foundation seed. A maximum of five harvest years is permitted for Certified seed. Dairyland Research International will maintain sufficient Breeder seed for the projected life of the variety.

The present invention contemplates using the Magnum VI plant, or part thereof, or an alfalfa plant having the physiological and morphological characteristics of the Magnum VI plant, as a source of hay, haylage, greenchop and dehydration.

Magnum VI was found to be highly resistant to: anthracnose (Colletotrichum trifolii), Aphanomyces root rot (Race 1) (Aphanomyces euteiches), bacterial wilt (Clavibacter michiganense), Fusarium wilt (Fusarium oxysporum), Phytophtora root rot (Phytophthora megasperma), Verticillium wilt (Verticillium albo-atrum) and moderate resistance to pea aphid (Acyrthosipon pisum).

Magnum VI is a moderately dormant variety similar to the fall dormancy 4 check. It expresses 7 and 41% better persistence than 5312 and Vernal respectively. Magnum VI winter survival is similar to that of the very winter hardy check. Flower color in the Syn. 2 generation is 90% purple, 10% variegated with trace amounts of cream, white and yellow. Magnum VI forage yield performance expresses a 7% advantage over 21 popular conventional varieties across 390 harvests. Its forage yield performance is 10% better than five popular ROUNDUP herbicide tolerant alfalfa varieties across 36 harvests.

The present invention contemplates using the Magnum VI alfalfa plant, or part thereof, or an alfalfa plant having the physiological and morphological characteristics of the Magnum VI alfalfa plant, as a source of breeding material for developing or producing an alfalfa plant in an alfalfa breeding program using plant breeding techniques. Plant breeding techniques useful in the developing or producing alfalfa plants include, but are not limited to, single seed descent, modified single seed descent, recurrent selection, reselection, mass selection, bulk selection, backcrossing, pedigree breeding, mutation breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, and transformation. Plant breeding techniques are known to the art and have been described in the literature.

As used herein, the term “plant” includes, but is not limited to, plant cells, plant protoplasts, plant cell tissue cultures from which alfalfa plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts thereof. “Plant part” includes, but is not limited to, embryos, pollen (pollen grains), ovules, seeds, flowers, pods, leaves, roots, root tips, anthers, and the like.

One may obtain alfalfa plants according to the present invention by directly by growing the seed Magnum VI or by any other means. An alfalfa plant having all of the physiological and morphological characteristics of Magnum VI can be obtained by any suitable methods, including, but not limited to, regenerating plants or plant parts from tissue culture or cuttings. The scope of the present invention is not limited by the method by which the plant is obtained.

The following non-limiting examples are intended to be purely illustrative.

Disease Resistance of Cultivar and Cultivar Components

The response of Magnum VI to various diseases was evaluated according to the “Standard Tests to Characterize Alfalfa Cultivars, 3rd edition, as amended July 1998”, approved by the North American Alfalfa Improvement Conference. The resistance or susceptibility of the cultivar to anthracnose (Colletotrichum trifolii), Aphanomyces root rot (Race 1), (Aphanomyces euteiches), bacterial wilt (Clavibacter michiganense), Fusarium wilt (Fusarium oxysporum), Phytophthora root rot (Phytophthora megasperma), Verticillium wilt (Verticillium albo-atrum), and pea aphid (Acyrthosipon pisum) were assessed. For each disease tested, appropriate check cultivars, including resistant and susceptible cultivars, were employed as controls. The results are presented in Tables 1 through 7.

For each type of disease tested, each line of plants was assigned to one of five classes of resistance according to the percentage of resistant plants as follows:

Class % Resistant plants
Susceptible  <6
Low resistant  6-14
Moderately resistant 15-30
